Hydraulic dampers consist of a pressure pipe, a piston rod with a special piston system and the damping medium of oil, which is why they are also called hydraulic dampers. Within the oil-filled pressure pipe is the piston rod with the special sealing and guiding package, which hermetically seals the interior of the hydraulic damper to the atmosphere - even under extreme environmental influences.
